Answer 1

I am using this code and its working well for me.

    ArrayList ImgArry = new ArrayList();
    path = objGetBaseCase.GetImages(TotImgIds);
    ImgArry.Add(SelImgId);
    ImgArry.Add(SelImgpath);//image name
    ImgArry.Add(SelImgName);//image path
    //path.Remove(ImgArry);
    List<ArrayList> t = new List<ArrayList>();
    if (newpath.Count > 0)
        t = newpath;
    t.Add(ImgArry);
    newpath = t;
    for (int i = 0; i < newpath.Count; i++)
    {
        ArrayList alst = newpath[i];
        newtb.Rows.Add(Convert.ToInt32(alst[0]), alst[1].ToString(), alst[2].ToString(), i);

    }
    dlstSelectedImages.DataSource = newtb;
    DataBind();

    path = objGetBaseCase.GetImages(TotImgIds);
    for (int i = 0; i < path.Count; i++)
    {
        ArrayList alst = path[i];
        tb.Rows.Add(Convert.ToInt32(alst[0]), alst[1].ToString(), alst[2].ToString(), i);

    }
    dlstImage.DataSource = tb;
    DataBind();
